NI MAX not showing softwares under "Add/Remove software" option

[HowardforNI]

Hello All,

I am trying to install LabVIEW Real-Time 2023 on (NI PXIe 8880 controller) through NI MAX using "Add/Remove software" option, the Labview Real-Time Software Wizard starts but there is no software to select means the softwares on the Host computer are not showing to install on the Remote system. See attached sample picture.
Is this a compatibility issue of Phar Lap ETS and LabVIEW Real-Time 2023 or some other reason? 

Thank you!

Your image is showing cRIO-9074. It is last supported on NI-RIO 19.6 and LabVIEW 2019. Reference: NI Hardware and Software Operating System Compatibility

For PXIe-8880, Pharlap is no longer supported as of LabVIEW 2022. You can use Linux RT instead. See Provisioning a Controller to the NI Linux Real-Time Operating System

Thank you ZYOng, I followed the steps in Provisioning a Controller to the NI Linux Real-Time Operating System

Now the system is in NI Linux Real-Time Run Mode. Next I will install the necessary softwares. 

Thank you again!
